25#  NDEBUG (C library)
26#     if defined asserts do not generate code.  This is commonly used
27#     as a command line option.
28#
29#  RTEMS_TEST_NO_PAUSE (RTEMS tests)
30#     do not pause between screens of output in the rtems tests
31#
32#  STACK_CHECKER_ON (RTEMS support code)
33#     If defined, stack bounds checking is enabled.
34#
35#  STACK_CHECKER_REPORT_USAGE (RTEMS support code)
36#     If this and STACK_CHECKER_ON are defined, then a report on stack usage
37#     per task is printed when the program exits.
38#
39#  RTEMS_DEBUG (RTEMS)
40#     If defined, debug checks in RTEMS and support library code are enabled.
41#
42#       
43#  PPC_VECTOR_FILE_BASE (ppc)
44#     This defines the base address of the exception table.
45#     NOTE: Vectors are actually at 0xFFF00000 but file starts at offset 0x0100
46#       
47#  PPC_ABI (ppc)
48#     This defines the calling convention (Application Binary Interface)
49#     used in this configuration.  EABI is the only one supported.
50#     This BSP was initially developed using the PowerOpen ABI.
51#
52#  PPC_ASM (ppc)
53#     This defines the assembly language format used in this configuration.
54#     ELF is the only one supported.
55#
56#  PPC_USE_SPRG (RTEMS PowerPC port)
57#     If defined, then the PowerPC specific code in RTEMS will use some
58#     of the special purpose registers to slightly optimize interrupt
59#     response time.  The use of these registers can conflict with
60#     other tools like debuggers.
